PS2, Line 9: The audio codec of Crota360 used is Cirrus CS42L42, different from Brya (Realtek ALC5682I)
           : There is no Reset pin on ALC5682 but CS42L42 is needed.
           : So we use GPP_B15 for the reset pin of CS42L42 controlled that make the power sequence well.
maximum line length for commit msg is 72 please
suggestion:
```
Crota360 is using a Cirrus CS42L42 for its audio codec; it
requires the reset pin to be deasserted in ramstage for proper
power sequencing.
```
